Freescale Semiconductor collaborated with OpenCon Systems to create a GPON reference-design kit that includes a turnkey software solution for ONTs (optical-network terminals) based on field-proven OMCI management technology that ships with Freescale's MSC7120 GPON device. The OpenCon software solution also leverages the device's on-chip DSP to support SIP-based VoIP voice-telephony services. The solution's software package includes user applications and management modules, a complete OMCI stack and APIs that interface to the Freescale device. The package enables communication between the GPON CPE and the central office at the service layer. The device is a dual-core voice-enabled GPON SoC that integrates a Power Architecture CPU, a StarCore DSP and a data-path engine to deliver a complete PON sub-system in a single device.
